What Is Business Property Relief?

Most of the people I sit down with are thinking about the house, the savings and the grandchildren. Business owners have all of that to weigh up, and a business on top. It is often the thing they have worked hardest on, and it is frequently the thing they have thought least about in terms of what happens after they are gone. Business Property Relief is one of the reasons it deserves proper attention.

I want to walk through what the relief is, what tends to qualify and what does not, and what changed in April 2026. I will be honest about the parts where the ground has shifted and you should take current advice rather than rely on a figure from a website. That includes this one.

What Business Property Relief is

Inheritance Tax is charged at 40% on the value of an estate above the available thresholds. For most estates that includes the nil-rate band of £325,000, which has stood unchanged since 2009. Business Property Relief, or BPR as it is usually shortened, is a separate relief that can reduce the taxable value of qualifying business assets before that tax is worked out.

The idea behind it is a reasonable one. When somebody dies owning a working business, the family should not be forced to break it up or sell it simply to settle a tax bill. Historically, qualifying business assets could attract up to 100% relief, which meant they could pass with no Inheritance Tax charged on that part of the estate at all. It is a valuable relief, and it has long been one of the main reasons a business owner should plan properly rather than leave things to chance.

What usually qualifies, and what does not

The relief is aimed at genuine trading businesses, not at wealth that happens to be parked inside a company structure. That distinction runs through the whole of it. Broadly, the sorts of assets that have qualified are these.

• An interest in a business you own, for example as a sole trader or as a partner in a partnership.
• Shares in an unquoted trading company, in some circumstances, where the company is genuinely carrying on a trade.
• Certain land, buildings or machinery used in a business you were a partner in or controlled, though these have generally attracted relief at a lower rate.

What does not qualify matters just as much. The relief is not meant for investment activity dressed up as a business. So a business that mainly holds investments, or one that deals in land or in shares, will usually fall outside it. If the company is really a way of holding property or a portfolio rather than trading, HMRC will look at it closely, and the relief may not be available at all.

The line between a trading business and an investment business is not always obvious, and it is exactly the sort of thing worth checking on your own facts rather than assuming. I have seen owners take the relief for granted only to find their particular set-up sat on the wrong side of that line.

The April 2026 reform

Here is the part where I have to be plain with you. The rules on Business Property Relief were reformed from April 2026. Where qualifying business assets could once attract up to 100% relief without limit, the position now is more restricted, so that relief above a certain level is more limited than it was.

I am not going to quote you a specific cap or a specific percentage on this page, because the detail is precisely the sort of thing that gets misremembered and misapplied, and I would rather you had it right than had it from me second hand. What I will say is that anyone whose estate includes a business of real value should treat the old assumption, that the whole lot would pass free of tax, as no longer safe. Take current professional advice on where you actually stand. If you already have a plan built on the old rules, this is a good moment to have it looked at again.

Why business owners need a will in the first place

Before any of the tax comes into it, there is a plainer point. A business owner needs a will. Without one, your share of the business falls under the intestacy rules, the same fixed order of relatives that applies to everything else. Those rules take no account of who actually runs the firm, who your business partners are, or who you would want to inherit your stake.

That can be a mess. A share in a working company can end up with someone who has never set foot in the place and has no interest in it, while the people keeping it going have no say. It can hold up the administration of the whole estate. A will lets you direct your business interest deliberately, to the people you choose, and it is the foundation everything else is built on. You can read more on our business wills page about how we approach this.

How a Business Will with a Business Property Relief trust works

This is where the will and the relief come together. There is a trap that catches owners who have not planned. Transfers between spouses and civil partners are exempt from Inheritance Tax, which sounds like good news. But if you simply leave your business outright to your husband or wife, any Business Property Relief on that asset is not really being used, because no tax was going to be charged on a spousal transfer in any case. When your spouse later dies, the business may no longer qualify, and the relief that was available on your death has been quietly wasted.

A Business Will with a Business Property Relief trust is designed to stop that happening. Rather than the business passing straight to your spouse, the qualifying interest passes into a trust on your death, so the relief is captured at that point. Your spouse can still benefit, but the value has been sheltered in a way that a simple outright gift would have thrown away. Used properly, alongside proper Inheritance Tax planning, it can make a real difference to what your family keeps.

I should be careful here, because this is exactly the kind of arrangement that has been affected by the April 2026 changes, and how much a trust can shelter now depends on the current rules. I would never promise a particular tax outcome, and I would be wary of anyone who did. What a trust of this sort can do is help preserve relief that would otherwise be lost, and put the arrangements in order so your executors and your family are not left guessing.

At Choice Wills a Business Will, which includes a Business Property Relief trust, is £1,350, agreed as a fixed fee before I begin. As with everything, the first conversation is free and there is no obligation to go ahead.

A word of caution to finish. This is an area where the law has moved recently and where the numbers matter, so please do not treat this page as the last word. If you own a business and you want to understand where you stand, do get in touch and we can go through your own circumstances properly.

Common questions

What is Business Property Relief?

Business Property Relief reduces the Inheritance Tax due on qualifying business assets when you die. Historically qualifying assets could attract up to 100% relief, but the rules were reformed from April 2026, so relief is now more limited above a certain level. Any business owner relying on it should take current professional advice.

What qualifies for Business Property Relief?

Broadly, an interest in a trading business you own, and in some cases shares in an unquoted trading company. Businesses that mainly hold investments, or that deal in land or shares, do not usually qualify. The detail matters and it is worth checking your own position with a professional.

Did Business Property Relief change in 2026?

Yes. The rules were reformed from April 2026 so that relief is now more limited above a certain level, where it was once more generous. I am not going to quote figures I am not certain of. If your estate includes a business, take current professional advice on where you stand.

Do I need a special will for my business?

If you own a business, it is sensible. Without a will your business share falls under the intestacy rules, which take no account of who runs the firm or who should inherit it. A properly drafted will lets you direct your business interest and can make use of relief where it applies.

How does a Business Will work?

A Business Will directs who inherits your business interest and can include a Business Property Relief trust, so that any qualifying relief is preserved rather than lost when the asset passes to a spouse. Choice Wills offers a Business Will including such a trust for £1,350, as a fixed fee.
